[SOLVED] Spring boot validation error request bad 400

I'm developing a crud API with a post method, when testing this method in my postman it returns the error

2023-02-15T13:34:35.528-03:00  WARN 8792 --- [nio-8080-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.bind.MethodArgumentNotValidException: Validation failed for argument [0] in public org.springframework.http.ResponseEntity<java.lang.Object> com.api.order_control.controllers.OrderController.saveOrder(com.api.order_control.dtos.OrderDto) with 2 errors: [Field error in object 'orderDto' on field 'doorNumber': rejected value [null]; codes [NotBlank.orderDto.doorNumber,NotBlank.doorNumber,NotBlank.java.lang.String,NotBlank]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [orderDto.doorNumber,doorNumber]; arguments []; default message [doorNumber]]; default message [must not be blank]] [Field error in object 'orderDto' on field 'block': rejected value [null]; codes [NotBlank.orderDto.block,NotBlank.block,NotBlank.java.lang.String,NotBlank]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [orderDto.block,block]; arguments []; default message [block]]; default message [must not be blank]] ]

I couldn't understand why my blank cannot work with this method and why this error. can anybody help me?

controller with post

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;

import java.time.LocalDateTime;
import java.time.ZoneId;

@RestController
@CrossOrigin(origins = "*", maxAge = 3600)
@RequestMapping("/orders")
public class OrderController {

    final OrderService orderService;

    public OrderController(OrderService orderService) {
        this.orderService = orderService;
    }

    @PostMapping
    public ResponseEntity<Object> saveOrder(@RequestBody @Valid OrderDto orderDto) {
        var orderModel = new OrderModel();
        BeanUtils.copyProperties(orderDto, orderModel);
        orderModel.setRegistrationDate(LocalDateTime.now(ZoneId.of("UTC")));
        orderModel.setPrice(70.8f);
        return ResponseEntity.status(HttpStatus.CREATED).body(orderService.save(orderModel));
    }
}

I had already had a blank error because I was using a float, but in this case "numberDoor" is just a string. What is the reason for this error?
